PATCH FOR TIRES.

Application filed February 28, 1921. Serial No. 448,289.

To f// whom. if viz/.zy concern.'

Be it known that I. EARL C. llaxnsoHUG, a citizen of the United States, residing at thc city ot' St. Louis and State ot' Missouri, have invented a new and uset'ul Patch for rlires, otl which the following is a specification.

This invention relates to inside tires.

An object of` the invention is to provide a novel and improved inside patch for tires adapted to be placed within the tire casing to strengthen and protect the inner tube,

patches for even though the casing be damaged by blownall punctures, y

out, rim cuts, stone bruises, or otherwise becomes `cut or perforated, thereby making it possible to continue the use of the damaged casing in actual service. Another object ot' the invention is to pro vide an inside tire patch of the character and for the purpose mentioned which will not slip from its position on the inner tube, or in the tire casing, and which eliminates all friction when the tire is properly inflated.

Another object of the invention is to provide an improved tire patch of the character j and for the purpose mentioned with novel equipment for lacing the patch around the inner tube, the entire structure of the patch being such that it will not damage the inner tube or the casing even though continuedin use until the tire is worn out.

Another object of the invention is to pro-` vide an improved inside tire patch ot the character and for the purpose mentioned with a permanently iiexible and 'pliable lacing connection for holding the patch around the inner tube. f

Another object of the invention is to pro- .vide a novel and improved inside tire patch which is characterized by the fact and condition that there are no metallic parts or elcments to contact with or injure the inner tube of the tire.

Other objects and advantages obtained by my improved inside tire patch will appear from the following description in which re ference is made to the dra-wing, showing featuresof the invention and in which-'- Fig. l is a sectional view of the tire patch upon an inner tube within a tire casing, the lacing devices being omitted to avoid confusion of lines in the drawing.

Fig. 2 is an elevation showing the preferred construction of 'my improved lacing for the tire patch.

' lengths as clearly shown in Fig. 2.

Fig. 3 is a sectional view on the line 3--3 of Fig. 2.

As shown, my improved tire patch comprises an arcuate sleeve, the curvature of which substantially'conforms to the curvature of the tube and of the inner side of the tire casing with which it is intended to be used. The sleeve may be ot any desired length and made of a laminated construction comprising two or more layers of flexible and pliable material secured together by vulcanizing, or by the use of appropriate cement, or otherwise. As shown in Fig. 3 the patch is composed of four layers l o fabricated material appropriately bonded together, but it will be understood that I do not restrict myself to the use of any laced edges of the sleeve so as to prevent injury tothe inner tube. One edge of the flap 2 is vulcanized, or cemented, or other-V wise firmly secured between the first and second plies or layers l, and has its other edge free or separate from the patch. As shown the tiap extends across the opening or space between the edges ot' the sleeve and lies against the inner surface ot' the sleeve forming a smooth inner surface and prevenu ing the lacing elements from contacting with the inner tube. The free side edge ot the flap 2 is attenuated so that no abrupt step or olf-set exists that might, be injurious to the inner tube ot' the tire. So, also, the edge of the inner ply or layer of the sleeve under 'which one edge of the Hap 2 is secured, is attenuated. Similarly, the ends ot the sleeve patch run together gradually thinning, or attenuated extremities 3, thus enabling the ends ot' the sleeve patch to shape themselves properly so that no damage will be caused to the tube on which the patch is Preferably, the flap Q is of greater length than the sleeve` so as to afford proper protection foifthe inner tube at the ends of the sleeve by preventing the tube from being pinched between the side edges of the tire, or otherwise injured.

My improved lacing' comprises a series of separate wire loops secured to the adjacent edges ot the sleeve. The arms 4 ot each loop are preferably .'of different The edge portions of the sleevexare embraced between thearms 4 of lthe loops, and the extremities 5 or' the loops are bent at `right angles tothe arms and imbedded in the 'sleeve material, but do not extend entirely" through the sleeve material as protruding ends would be detrimental.V The series'oi loops are arranged to overlap, as shown, the loops of each series extending between the loops 'of adjacent series in alternate rela.-

tion as shown in Fig. 2. Preferably the loops are arranged `so that the long arms and the short arms thereof 'are on. alternately opposite sidesof *the material, in

A ner tu e at the proper position to cover or extend across the damaged part .of the tire casing. The tire may then be mounted on the wheel and-inflated. When the tire isl properly inflated thetube will not slip from its proper adjustment and all of the inetalhc parts ofthe patch, comprising the fasteners 4 are prevented from coming in con` tact with the tube. 'Y

Patches of this character may be made satisfactorily of fabric carcasses, or of fabric cord carcasses. The thickness Aof the patch in such cases depends upon the thickness of the .carcasses used, since different tires are made of'diferentV thickness. The patch possesses. the characteristic of complete iexibility and pliability, /vvithperfect-V ly smooth inner surfaces sol asjto cause no injury by abrasion or by pressure to the inner tube. l l

I do not restrict myself to unessential parti'eulars, since the construction and arrangement may be varied without'departing from the principle of tlhe'invention.

The invention-completely 'serves all of its' intended objects `and purposes, and is very' durable and of comparatively inexpensive construction.

`What I claim and desire to secure by Let' An 'inside tire patch, comprising a split` sleeve composed of layers of fabricated material bonded together and fhaving their edges in radial alinement, -a series of sepa'- rate loops secured to lthasleeve atea'ch side of the split, a non-.metallic pliable rodpass ingthrough all'of said loops between the edges of the sleeve to bind the sleeve around anv inner tube, and a flap having one'edgev f t e overlapped by one of the layers o 'sleeve at one side ofethe -split beyond the ends of the series of loops atthat side of the split, said flap extendlng across the split 4beyond the opposite ends of the. loops at the opposite 'side of the split, and said Hap EARL o. HAruscHUofT extending beyond each end `of 4the sleeve. j
